This application is a continuation-in-part of U.S. patent application Ser. No. 10/222,079 entitled “Methods and Apparatus for a Discrete Vapor-Dispensing Device” filed Aug. 16, 2002 which is incorporated herein by reference.
This invention relates, generally, to vapor-dispensing devices and, in particular, to a vapor-dispensing device which integrates with a receptacle in a discrete manner.
It is often convenient to use an available receptacle, for example, a conventional household electrical outlet, as a source of electrical power for systems configured to perform some type of environment-altering task. Known environment-altering systems include, for example, plug-in air-fresheners, vapor-dispensing devices, plug-in ultrasonic pest control devices, night-lights, ionizers, and the like.
Due to the location and accessibility of conventional wall outlets, and the size and shape of known vapor-dispensing devices, it is common for such devices to be relatively conspicuous when plugged into a wall outlet. In the case of household plug-in air-fresheners, for example, this may give rise to unfortunate conclusions in the minds of visitors with respect to the overall quality of air in the home.
In some instances it may therefore be desirable to enhance the extent to which vapor-dispensing devices integrate or blend in with their environment. The level of discreetness is generally related to a device's overall geometry and the manner in which the device contacts the wall and/or receptacle to which it is connected.
In addition to this aesthetic discreetness, it would also be advantageous to provided an environment-altering apparatus with enhanced functional discreetness. That is, there is a need for vapor-dispensing devices which do not eliminate, reduce, or otherwise alter a user's access to the functional features of the receptacle. In the case of plug-in air-fresheners, for example, it would be advantageous to provide an air-freshener wherein access to all or most of the receptacle's outlets are substantially maintained.
In general, the present invention provides a vapor-dispensing device or other environment-altering apparatus configured to integrate with its environment in a discreet manner. The apparatus may accomplish this discreetness in a number of ways—for example, by blending in with one or more components of the environment (e.g., a wall or other surface), by covering or otherwise occluding all or a portion of the receptacle, and/or by appearing to be something other than an environment-altering device.
One way the environment-altering device may blend in with its environment is by including a housing configured such that a cross-section orthogonal to and through the perimeter of the housing defines a blending contour from the front surface to the wall outside the perimeter of the electrical receptacle.
Another way the device may accomplish blending with its environment is by exhibiting a particular color, texture, and/or geometry which matches or is otherwise thematically consistent with the environment in which the device is to be placed.
Yet another way the environment-altering device may blend in with its environment is by making contact with a wall or other surface in the vicinity of the receptacle. In one embodiment, for example, the device includes a housing having at least two antipodal points on the perimeter of the housing that make contact with the wall outside the perimeter of the receptacle faceplate when the device is connected to the receptacle.
In accordance with a further aspect of the present invention, a vapor-dispensing device blends into its environment by exhibiting a low profile normalized in terms of an inter-outlet dimension or one or more other suitable dimensions.
The environment-altering device may also be configured to entirely or partially cover the electrical receptacle in a number of different ways. In accordance with a one embodiment of the present invention, for example, the device may include a housing whose perimeter substantially encompasses the perimeter of a electrical receptacle's faceplate when the vapor-dispensing device is connected to the electrical receptacle.
In accordance with a further aspect of the present invention, a vapor-dispensing device covers the receptacle by including a housing whose aspect ratio is substantially similar to the aspect ratio of a receptacle faceplate, and whose center is substantially coincident with the center of the faceplate.
In accordance with another aspect of the present invention, discreetness is achieved by configuring the environment-altering device such that it appears to be something other than an environment-altering device.
In accordance with one embodiment of the present invention, for example, an environment-altering apparatus is configured to mimic an electrical receptacle having an outlet pattern. The environment-altering apparatus has a front surface which includes an outlet pattern substantially corresponding to the outlet pattern of the electrical receptacle, and a plug configured to interface with the electrical receptacle. A device configured to modify one or more attributes of the environment is interposed between the front surface and plug pattern. These attributes include, for example, aromatic vapor density, insecticide vapor density, ambient light intensity, ionic air content, ultrasonic frequency intensity, and the like.
The subject invention will hereinafter be described in conjunction with the appended drawing figures, wherein like numerals denote like elements, and:
Systems and methods in accordance with the present invention generally provide a vapor-dispensing device or other environment-altering apparatus configured to integrate with its environment in a discreet manner, e.g., by blending in with one or more components of the environment, by covering or otherwise occluding all or a portion of the receptacle, and/or by appearing to be something other than an environment-altering device.
Environment 130 corresponds to any defined space, whether open or enclosed by one or more surfaces, walls, ceilings, floors, or other solid or fictitious boundaries, which receives the evaporated material. For example, environment 130 may correspond to a residential room (bedroom, bathroom, kitchen, etc.), commercial space (factory floor, office cubicles, etc.), automotive enclosure (car, truck, recreational-vehicle), airline compartment, or any other space in which it is desirable to deliver a vapor.
In accordance with one embodiment of the present invention, an environment-altering apparatus is configured to give the appearance that it is something other than an environment-altering apparatus. For example, the environment-altering apparatus may be configured to mimic an electrical receptacle having an outlet pattern. In this embodiment, the environment-altering apparatus has a front surface which includes an outlet pattern substantially corresponding to the outlet pattern of the receptacle, and a plug configured to interface with the electrical receptacle.
For example, referring now to
A device 210 configured to modify one or more attributes of the environment is suitably interposed between (and/or to the side of) the front surface 204 and plug pattern 204. Environmental attributes modified by device 210 include, for example, aromatic vapor density, insecticide vapor density, ambient light intensity, ionic air content, ultrasonic frequency intensity, and the like. In an embodiment wherein device 210 corresponds to a fragrance delivery device, it may also include one or more components (e.g., wicks, capillary tubes, and the like) which provide a means for at transporting volatizable material from one location to another (e.g., from a reservoir to a evaporation pad or eminator), and/or one or more components (eminator pads, secondary wicks, and the like) which provide a surface or surfaces from which the transported material undergoes mass transfer or evaporation to environment 120.
In an embodiment wherein receptacle 120 corresponds to an electrical power outlet, it is advantageous to utilize this power source to provide any electrical functionality required by the fragrance delivery device. For example, fragrance delivery device may include one or more eminators or heating elements designed to control the rate at which the volatizable material evaporates into the environment. In such a case, delivery device 210 may include various terminals, wires, conductive traces, plugs, and other such components facilitating interface and power delivery to receptacle 120. In a particularly preferred embodiment, for example, delivery device 210 includes a resistive heating element that is thermally coupled to an eminator pad or wick which communicates with a volatizable material.
Although the vapor dispensing device 100 of
It will be appreciated that the present invention is not limited to electrical receptacles. Indeed, receptacle 120 may comprise any suitable structure configured to provide electricity, data, or any other power and/or information source to vapor-dispensing device 100 through a suitable interface. For example, suitable receptacles include RJ-11 and RJ-45 jacks used in connection with high-speed data transfer (and analog telephone communication), co-axial connectors used in connection with electrical and optical cable networks, and any other receptacle design now known or developed in the future.
Notwithstanding the nature of receptacle 120—i.e., whether and to what extent receptacle 120 is configured to supply electrical current—delivery device 210 may be passive, active, or selectably switched between active and passive modes. The term “passive” in this context, as applied to delivery devices, refers to those devices which substantially depend upon ambient conditions to deliver a fragrance or otherwise give rise to a modification of the environment. Such ambient conditions include, for example, ambient thermal conditions (e.g., wall surface temperature and air temperature) and ambient air flow, (e.g., air flow resulting from free convection as well as the movement (if any) of fans, individuals, and other entities within the environment). The term “active” in this context refers to devices that are not passive, e.g., devices which employ integrated fans, heating elements, and other such devices.
In the event that delivery device 210 is an active device, any power source required by the device may be intrinsic to receptacle 120, e.g., the 120 V source of a standard wall outlet, or extrinsic to receptacle 120, e.g., supplied by a battery, solar cell, or other such device incorporated into or otherwise associated with delivery device 210. Alternatively, power may be supplied by a combination of intrinsic and extrinsic sources and/or may be incorporated into a refill component, described in further detail below.
In order to achieve the goal of appearing to be something other than a vapor-dispensing device, the device may be designed to mimic not only an electrical receptacle, but any number of other objects which might typically appear in the target environment. For example, the vapor-dispensing device might be configured to mimic a wall switch, a multi-outlet power strip, a night-light, or any other suitable object.
As mentioned above, discreetness of the environment-altering device may also be achieved by configuring the device such that it blends in with its environment. This blending may be accomplished, for example, by including a housing configured such that a cross-section orthogonal to and through the perimeter of the housing defines a blending contour from the front surface to the wall outside the perimeter of the electrical receptacle.
In accordance with a further aspect of the present invention, a vapor-dispensing device blends in with its environment by including a housing wherein at least two antipodal points on the perimeter of the housing make contact with the wall outside the perimeter of the receptacle faceplate when the device is connected to the receptacle.
In accordance with a further aspect of the present invention, a vapor-dispensing device has low-profile dimensions. More particularly, referring now to
In order to achieve the goal of blending in with the environment, any number of other attributes of the device may be designed to match or be thematically consistent with one or more attributes of the environment. For example, the device's color, texture, and/or geometry may be selected to better blend in with the wall, furniture, or other components of the environment.
Discreetness of the environment-altering device may also be achieved by configuring the device such that it covers all or a portion of the receptacle. In accordance with one aspect of the present invention, for example, a vapor-dispensing device substantially covers the receptacle by including a housing whose perimeter substantially encompasses the perimeter of a electrical receptacle's faceplate when the vapor-dispensing device is connected to the electrical receptacle.
More particularly, referring to the four exemplary configurations shown in
Delivery device 210 suitably includes one or more removeably attached refill components. That is, referring to
In accordance with one aspect of the present invention, a refill component is provided which allows vapor-dispensing device to mimic an electrical receptacle. For example, a refill component comprising a refill body having a volatizable material provided therein may be configured to be inserted behind the front surface of the device such that it is substantially concealed by the front surface. In accordance with one aspect of the present invention, the refill has a perimeter that is encompassed by the perimeter of the housing.
In accordance with another aspect of the present invention, the refill is configured such that it does not significantly obstruct the receptacle's outlet pattern 504. In one embodiment, for example, this is accomplished by providing a refill component 1502 that at least partially surrounds one or more outlets on the receptacle (variously shown in FIGS. 15A-15C). In the event that the delivery device is used in connection with a standard electrical receptacle, it is desirable for refill 1502 to encompass two or more sides of the outlet pattern (FIG. 15A). To the extent that it is advantageous to supply the greatest possible volume of volatizable material, the refill may be configured as a rectangular ring that completely surrounds the outlet pattern 504 (FIG. 15B). Alternatively, the refill may be configured in a ‘U’ shape to allow refill 1502 to be slideably removed from the device (FIG. 15C).
Although the invention has been described herein in conjunction with the appended drawings, those skilled in the art will appreciate that the scope of the invention is not so limited. Modifications in the selection, design, and arrangement of the various components and steps discussed herein may be made without departing from the scope of the invention.
